Here we present NeuroVault — a web based repository that allows researchers to store, share, visualise, and decode statistical maps of the human brain. NeuroVault is easy to use and employs modern web technologies to provide informative visualisation of data without the need to install additional software. In addition it leverages the power of the Neurosynth database to provide cognitive decoding of deposited maps. NeuroVault is also a resource for researchers interested in conducting meta- and coactivation analyses. All of the data is exposed through a public REST API enabling other services and tools to take advantage of it.
